National Instruments IMAQTM Manual De Usuario

image enhancement

The process of improving the quality of an image that you acquire from 
a sensor in terms of signal-to-noise ratio, image contrast, edge definition, 
and so on.

image file

A file containing pixel data and additional information about the image.

image format

Defines how an image is stored in a file. Usually composed of a header 
followed by the pixel data.

image mask

A binary image that isolates parts of a source image for further processing. 
A pixel in the source image is processed if its corresponding mask pixel has 
a non-zero value. A source pixel whose corresponding mask pixel has a 
value of 0 is left unchanged.

image palette

The gradation of colors used to display an image on screen, usually defined 
by a CLUT.

image processing

Encompasses various processes and analysis functions that you can apply 
to an image.

image source

The original input image.

imaging

Any process of acquiring and displaying images and analyzing image data.

IMAQ

Image Acquisition.

inner gradient

Finds the inner boundary of objects.

inspection

The process by which parts are tested for simple defects such as missing 
parts or cracks on part surfaces.

inspection function

Analyzes groups of pixels within an image and returns information about 
the size, shape, position, and pixel connectivity. Typical applications 
include quality of parts, analyzing defects, locating objects, and sorting 
objects.

instrument driver

A set of high-level software functions, such as NI-IMAQ, that control 
specific plug-in computer boards. Instrument drivers are available in 
several forms, ranging from a function callable from a programming 
language to a VI in LabVIEW.

intensity

The sum of the Red, Green, and Blue primary colors divided by three, 
(Red + Green + Blue)/3.
